Even now, male birth control still sounds like “you are basically offering people a potential lawsuit,” said Heather Vahdat, executive director of the Male Contraceptive Initiative.By continuing to develop, test, and hopefully one day market a male contraceptive, they aim to usher in a new vision of what feminist bioethicist Lisa Campo-Engelstein has called “contraceptive justice” — a world in which every person has a safe, reliable, and even likeable means of controlling reproduction.“They said, ‘If it meant I didn’t have to use a condom, I’d take one in 100.’” The World Health Organization now estimates about 39% of men in the U.S. would use a new contraceptive within a year of its release.This is really working so much better than we expected.” Science has promised that male birth control is about five to 10 years away since at least the 1970s.The first trial involved giving male participants weekly injections until they had zero detectable sperm left."
